We propose an architecture using the 60 GHz Radio over Fiver along with a novel concept of forming Extended Cells (EC). Since in the indoor environment , the propagation of millimeter wave signals is strongly hindered by walls, people, furniture, etc., a mobile user might experience frequent loss of connection as soon as one movers from one cell to antother. With ECs one can create sufficient overlap areas between cells, thus ensuring a semaless communication environemtn to achieve lesser handovers and call drop. We illustrate the effectivieness of the proposed architecture throught simulation. We continue further to model the mobility of users in the indoor environment to arrive at an expression to find the call blocking probability.@en

This paper addresses the issues of desiging an infrastructure to support seamless in-building communication at the 60 GHz band. Recently, the 60-GHz band has received much attention due to its 5-GHz of available spectrum. Howevver, the propagation of signals in this band is strongly hindered by attenuation and line-of-sight requirements. The situation gets worse in the in-building environment where signal propagation is obstructed by physical objects such as walls, furniture etc. In this paper, we present a novel Radio over Fiber (RoF) architecture that is cost-effective and is able to deliver high data-rate of the order of gigabits. To ensure a seamless communication environment at the 60GHz band, we propose the concept of Extended Cells (EC) in order to create sufficient overlap areas. Finally, we illustrate the effectiveness of the proposed architecture by simulating an in-building network at the 60 GHz band employing the RoF and EC concepts.@en

Radio over Fiber (RoF) techniques have been long recognized as the promising solution for indoor networking at millimeter-wave bands. We discuss the possbile deployment scenarios of an RoF network for indoor environment. In this paper, we try to find the answer to the question as to which Medium Access Control (MAC) protocol is suitable for an RoF network. To substantiate our claims, performance analysis of two popular MAC protocols employing R0F - IEEE 802.11 representing the distributed control protocol family - is presented. We show that RoF techniques canb e applied to both protocols. We also show that the centralized control is an appropiate candidate fro RoF networks. This study is expected to contribute to the speedy deployment of RoF for indoor network deployment.@en
